This infographic appeals to a sense of activism about global warming and habitat depletion.  It also gives useful information about recent findings in science/current events as well as interesting topics in biology, speciation and evolution.  

In order to activate the viewer, the graphic seeks to evoke a sense of anxiety, fear, and humor: anxiety not only about environmental degradation, but more immediately due to visualizing the size of the hybrid species in reference to the the human figure.  The speculative ligizzly appeals to humor but also serves as a warning about further environmental negligence, thus capturing the attention of those engaged in social action.  The topic is broad enough to pique the interest of people of all fields and ages, but at the same time appealing to two specific groups: the environmentally aware and those with some interest in biology/evolution.
